Strapi, an open-source Node.js headless CMS, facilitates the development of APIs and content management through collections and single types. It inherently supports relational database modeling, allowing users to establish various relationships such as one-to-one, one-to-many, many-to-many, and polymorphic relationships among Content Types. These relationships are set via the Strapi admin UI or directly in the Strapi project files. The article further elaborates on using these relationships in a practical application by developing a Q&A app, akin to Quora, using Strapi for the backend and Next.js for the frontend. This application showcases real-life implementations of the relationship types, demonstrating how questions, answers, and comments can be structured and managed within the system. The process involves setting up Strapi collections, defining models and relationships, and integrating them with frontend components to create a functional web application that allows users to ask questions, submit answers, and comment on answers, highlighting Strapi's capabilities in managing complex data relationships.
